The Winston Hybrid PV and BESS project is a proposed 306 MW hybrid solar and battery energy storage system development in Kern County, California. The project consists of a 204 MW solar photovoltaic array coupled with a 102 MW battery energy storage system. It is located within the California Independent System Operator (CAISO) region and is interconnected to the PG&E utility grid at the Midway 115 kV point of interconnection.
The project, identified as CAISO-1751 in the CAISO interconnection queue, entered the queue on April 15, 2020, and has a proposed commercial operation date of December 10, 2028. The Interconnection Agreement (IA) for the project has been executed. The project has appeared in recent news coverage.
